Week 3 Simplifying Radical Expressions

3: Write each mixed radical as an entire radical (page 100)




When I first do this question,I was confused by the difference of the mixed radical and entire radical. I think the most difficult part is the index part becasue there is a tube and I don’t know how to solve this. And we only learned how to simplify in Grade 10. My¬† understanding is that when we solve this type of question, we need to multiple all the numbers outside the root, the index and so as the radicand together. When there is a tube (3), just multiple 3, we don’t have to multiple three times becasue that’s not the exact meaning of tube. The most important thing is that we should be careful when we do the calculating.
